Quick question on the forester exhaust guys. Tried to do a search on this without luck.

MY new girlfriends's 2000 forester has a horrible exhaust leak right by the resonator. I have a stock 2002 wrx catback in good condition from when i put my aftrermarket on turboback on. Any idea if these are interchangable? I know all about what will and wont work on my car but looks like with this new chick I am going to have fun learning all about the forester now.

any help is apreciated
